THC + Breastfeeding?

If you’re gonna be rude let’s just go ahead and say DON’T comment in the first place.. I had my baby two weeks ago, and I was wondering what the effects of thc in breastmilk are from those mama’s who have smoked while breast feeding / pumping & feeding. Right now little one is on a mix of formula + breastmilk fed, but my anxiety + depression is starting to creep back up slowly, and marijuana was my prime source of treating & coping with my mental health issues prior to pregnancy & throughout the first half of carrying our girl. Does it stay in my breastmilk as long as its in my system? Does it have any effect on the baby other than making them a little more sleepy after feeding time as I have heard from other mamas? Again.. if you are gonna be rude just don’t comment on it. I’m not currently smoking, I’m simply looking into what effects would arise if I decided to start again.
